title: [Duplex sonography. Examples of its use in otorhinolaryngology].
abstract: Duplex sonography not only provides the ENT specialist with valuable information on topographic relations of soft tissue tumours with the main blood vessels of the neck but provides also information on the blood flow in these vessels. It makes it possible to draw reliable conclusions on vascular anomalies or dislocation of the vessels, on affections of the vascular wall, on restricted patency of vessels due to the action of a tumour (compression, penetration) or inflammation (thrombus) or changes in the flow through the jugular vein conditioned by impaired passage in the S-shaped sinus. In some instance ultrasonic examination is a valuable method for evaluation of the dynamic and further development of the basic disease and can replace classical arteriography or phlebography.
